Embodiment Construction

[0033] figure 1 with figure 2The conventional shapes of a watersports float are shown from above (the view is generally called "profile") and from the side (the views are usually called "foil" and "sickle curve"), respectively. In the traditional method, as in which the floaters are represented by cross-section image 3 As shown, the float is manufactured from a foam block 1 forming a preformed core covered with a layer 2 of glass fiber reinforced resin.

[0034] Foam blocks usually have a density of 50kg / m 3 polyurethane foam, but also extruded expanded polystyrene foam. The core may also have a "sandwich" structure, ie a structure formed by an assembly of layers of different kinds.

[0035] The invention described below can be applied to any type of core.

[0036] The method of the present invention for wrapping a preformed core having two faces and a lateral edge connecting the two faces involves thermoforming and direct application of a float of polymeric material in...

Abstract

The invention relates to the coating of preformed objects with sheets of polymer material. More specifically, the invention relates to a method for coating a preformed core (1) having two faces and an edge around the periphery of the core, which edge links the two faces, said method comprising the thermoforming of a polymer material. The coating is formed by the heating, gluing and vacuum application of the two sheets of polymer material (20, 30) which are applied successively to the two faces of the core (1) in order to cover same completely. The invention also relates to an automatic machine for carrying out said method and to the resulting product. The invention can be used to produce finished products, in particular surfboards, furniture or display objects.

Description

technical field [0001] The invention relates to the field of manufacture of finished products by means of automatic thermoforming methods based on cores of arbitrary shape protected and finished by a coating of polymeric material in order to reinforce and / or protect and / or decorate the finished product . The invention is particularly suitable for sports and leisure products for water sports of the buoyant type, but also for decorative elements, furniture and point-of-sale displays or other types of accessories. Background technique [0002] There are a number of traditional cladding methods that utilize polymeric materials to finish products of arbitrary shape. [0003] In the particular field of surfboards, the oldest traditional method is the manual method: a buoyant element having the desired shape defined by a core piece finished by hand sanding is wrapped with fiberglass impregnated with polyester or "epoxy" resin. Membrane wraps which form the outer stiffening shell ...
